Dark screen and can't unlock
A new phone(Samsung A12 ) was purchased 2weeks ago on which the teamviewer host program was installed. First week the program worked without problems. I normally can connect and unlocked the phone(Samsung A12)with remote control from my phone (samsung s10e ). Now I can connect to the phone, but the screen can not be unlocked, it is always dark. I press any buttons the screen does not work to "wake up" as before. In the settings was not any correction. Why did the program stop working remote control( can't unlock)?
When phone is unblocked I can remote him. How to fix this problem( unlocked phone then I am connected with Team viewer)?
